6 FUNCTIONS FOR TRANSMIT I ∂TX function [RIT/∂TX] [∂TX] D ∂TX monitor function [CLEAR] [XFC] I Monitor function [MONI] [MONI GAIN] The ∂TX function shifts the transmit frequency up to ±9.999 kHz in 1 Hz steps (10 Hz steps when cancelling the 1 Hz step readout) without moving the receive frequency. • See (3 on p. 1-11 for function description. q Push [∂TX]. • " " appears. w Rotate [RIT/∂TX]. e To reset the ∂TX frequency, push [CLEAR] for 1 sec. • Push [CLEAR] momentarily to reset the RIT frequency when the quick RIT/∂TX clear function is ON. (p. 12-1) r To cancel the ∂TX function, push [∂TX] again. • " " disappears. When the ∂TX function is ON, pushing and holding [XFC] allows you to monitor the operating frequency directly (∂TX is temporarily cancelled). ✔ For your convenience- Calculate function The shift frequency of the ∂TX function can be added/subtracted to the displayed frequency. ➥ While displaying the ∂TX shift frequency, push [∂TX] for 1 sec. The monitor function allows you to monitor your transmit IF signals in any mode. Use this to check voice characteristics while adjusting SSB transmit parameter. (p. 12-4) The CW sidetone functions regardless of the [MONI] switch setting. q Push [MONI] to switch the monitor function ON and OFF. • [MONI] indicator above this switch lights green. w Rotate [MONI GAIN] for the clearest audio output while pushing [PTT] and speaking into the microphone. NOTE: When using the VOX voice delay, turn the monitor function OFF; or transmitted audio will be echoed. 6-4
